Property Value

This property may also be true if this element has been moved within the logical tree such that it has a new parent element, and therefore becomes reloaded again.

This property is useful if you also are using BeginInit and EndInit. Elements in the logical tree that is loaded by a XAML processor are assured to be initialized. Elements not in the logical tree are initialized when EndInit is called. In absence of any specific handling of BeginInit and EndInit, this will happen as soon as the constructor returns the initialized result.
